After leaving computer in an idle mode for around 10-15 min, it disconnects from the Internet and loses its connectivity. I have to restart the system in order to reconnect.
I’m using Network Manager to connect to Internet.
Any thoughts on that?

i’d say it is probably being disconnected by your ISP, or however you
are connected to the net…
three questions:
-
which way are you connected: would that be (dialup, dongle,
free-public wi-fi, usbstick, DLS through a ‘modem’ provided by your ISP,
through a community feed in (say) an apartment block, school dorm or
office network, through a cable TV feed, or what??? -
have you had this problem from the first day of 12.2, or did it just
begin? if so, what changed (method of connection maybe?) -
why did you not post this to the networking forum?

It’s DSL, connection by username and password through ADSL Router (Billion). It’s the software problem cause after I’m disconnected, I can’t reconnect. When I open Network Manager after disconnection in order to reconnect, DSL connection disappears from network management widget. There’s only data that it is there in Network Manager but it’s not possible to use it. It appears again after reboot. I noticed this problem a few days ago, but I don’t know if it happened before… I didn’t notice.

i’d suggest you click on the “Report” icon near the bottom of this
message and in that contact the moderators and ask them to move this
thread to the networking forum (which is where the real networking gurus
hang out–well, for sure i wouldn’t know how to help you trouble shoot
your system…)
well, until you get help i’d recommend you avoid all those re-boots and
instead in a root terminal issue this command
/etc/init.d/network restart
that should case the network to go down and then restart…which should
then give you a new connection, like you would get when you reboot.
hmmmmmm, well i do not know if that command will work on a 12.x systemD
setup…try it and see…if it does not work you will (hopefully) get
better advice in the correct forum!!

You can also disable/re-enable networking from within NM by simply unchecking and checking the “X” for “Enable Networking.”
If you have any other devices or machines that connect through the same DSL modem, it might be helpful if you notice the same behavior. I haven’t seen for a long time now, but i can remember that ISPs did configure their DSL (not just dialups) modems to disconnect clients due to lack of activity.
Try pinging your Gateway(and any other Hosts in your LAN if they exist) to verify the problem really is your system and not your ISP
Is Internet connectivity the only thing that’s broken? if your machine is going to sleep, consider modifying or disabling power settings.
HTH,
TSU
I would go by steps (since I was setting a router the other day). In a lot of modems if you go into the interface (generally through 192.168.1.1 or similar, pls see your manual) you check for “connect on demand”. This means that the modem-router or router may disconnect after 15 min if it does not sense activity. Please check this to be dead sure that it is not your modem settings.
I have already tried with re-enabling network with unchecking and checking option, but no success. Since my power settings due to some other problems are shut down and not running at all, Internet Connectivity seems to be the only thing that is broken.
No, it’s not that, cause I use other systems as well and I don’t have that kind of issue.
As an addition,
I belive it’s the software problem cause after I’m disconnected, I can’t reconnect. When I open Network Manager after disconnection in order to reconnect, DSL connection disappears from network management widget. There’s only data that shows connection is there in Network Manager but it’s not possible to use it. I can use it again after reboot. I noticed this problem a few days ago, but I don’t know if it happened before… I didn’t notice.
I googled through with “billion router disconnects” and found quite some troubled users when the provider switched to adsl2 standard. I do not know if this is your case.
To be clear: I suppose you are not using particular setups like vpn, strongswan or others when this happens.
Question:
Version of O.S.? Version of KDE? Version of the Networkmanager?
Does this happen regardless if activity is on the modem or not?
The other machines do run linux as well? Or if not which OS?
What net related software do you run while the disconnect happens?
Is this a laptop or a PC?
Do you have another LAN port driven by another NIC to check for hardware failure of your lan card?
Did you try to (stupid but may be) change the Lan cable?
Did you try to change the cable to another Lan port of the modem?
Did you try to run a life CD of another O.S. to see whether the same happens?
Guys I had a major problem with OS, so I re-installed my system, and now everything seems OK.
Maybe that was causing these disconnections. I tested it again and it didn’t disconnect… If it happens again I’ll come back to this thread.
Thanks.
